The air is subjected to a secondary treatment by the activated carbon block 211 to purify the air. The purified air is input into the air guide pipe 6 and then into the interior of the film blowing molding component 1, and is evenly blown into the interior of the film to be formed. The filtering device 2 solves the problem of the blowing device of the traditional film blowing machine. The blowing air source is basically provided by the air compressor 4, but the air inlet end of the air compressor 4 is exposed to the air. When the air carrying dust is used in the blowing operation, the dust will adhere to the inside of the blown film, reducing the production quality problem.

[0036] Through the fixing device 3, when it is necessary to place and remove the film scraps produced during production, the operator first places the film scraps in the placement box 32. When a certain amount of film scraps in the placement box 32 is collected, the handle 36 is pulled away from the inside of the placement box 32. The handle 36 is pulled to move the U-shaped plate 35 away from the inside of the placement box 32, making it easy to remove the film scraps from the placement box 32. Through the fixing device 3, the problem of the blowing device of the traditional film blowing machine is solved, and there is no place to place the film scraps during film production, which reduces the problem of film scrap recovery.
